Mastering Xamarin.Forms - Second Edition

By: Ed Snider

Overview of this book

Discover how to extend and build upon the components of the Xamarin.Forms toolkit to develop effective, robust mobile app architecture. Starting with an app built with the basics of the Xamarin.Forms toolkit, we'll go step by step through several advanced topics to create a solution architecture rich with the benefits of good design patterns and best practices. We'll start by introducing a core separation between the app's user interface and the app's business logic by applying the MVVM pattern and data-binding. Then we will focus on building out a layer of plugin-like services that handle platform-specific utilities such as navigation and geo-location, as well as how to loosely use these services in the app with inversion of control and dependency injection. Next we'll connect the app to a live web-based API and set up offline synchronization. Then, we'll dive into testing the app logic through unit tests. Finally, we will setup Visual Studio App Center to automate building, testing, distributing and monitoring the app.

App Monitoring

In the mobile development world, it is very important to iterate fast—users want new features and expect quality, and if you cannot deliver on those expectations, you will certainly feel it in your ratings and reviews. One of the best ways to ensure that you are shipping quality apps and features is to employ DevOps. DevOps is where the technical and operational sides of app development meet. Proper DevOps integrates business operations with tools, resulting in a more automated and continuous release process. DevOps tools typically combine continuous integration and delivery (CI/CD)
automation of the building, testing, and distributing of your app and monitoring it. CI/CD and monitoring together create a seamless loop where CI/CD provides an output of testable features, and monitoring provides an input of feedback and analytics on those features. This...
